Central Demolition adds increased washing capacity for recycling C&D waste

Bonnybridge, Scotland, based contractor Central Demolition has extended its recycling capabilities through the addition of a new washplant supplied by UK Powerscreen distributor Blue Machinery. According to Central, the new plant enhances its existing recycling plant and creates a tandem configuration of specialist recycling equipment to process large volumes of C&D waste to produce a wide range of saleable reclaimed materials. It is now confident at it is achieving a recycling rate of between 90 and 95% of the thousands of tonnes of demolition waste, inert materials, soils and skip waste fines received from around Scotland that it processes at its Bonnybridge recycling station.

The new plant consists of a Powerscreen Warrior 800 mobile screen that is used as a pre screener, from which waste is conveyed to a Powerscreen 1400 feeder, a 5032 conveyor and an overband magnet for ferrous removal and then to a Powerscreen Powerscrub 120R logwasher. The logwasher carried out intensive mixing and scrubbing, with the resultant discharge fed onto a rinse screen and then to a Powerscreen Chieftan 1400 for separation and stockpiling in 40 mm, 20 mm and 10 mm sized clean recycled aggregates. Contaminats removed by the Powersrub are floated off and dewatered on a trash screen ready for sorting and reclamation.

Sand, slurry and dirty wash water are transferred to a Powerscreen Finesmaster 60 where clays, silt and sand are removed, with water discharged to settlement ponds for reuse within the washing system. Sand is discharged from the Finesmaster, dewatered and stockpiled by a Powerscreen T 4026 conveyor/stockpile.
